about hard water, you need to
know if you have it and, if so, how
hard it is.
If you live in a municipal area,
contact your water company.

some suburban areas, contact your
county agent.
The answer will be "you have 'so
many grains' per gallon" and
means this:
O to 3 grains per gallon—SOFT,
4 to lograins-mm, 11 to 19
and over—EXTREMELY ~RD.

If your water is SO~, you have no
problem. You can use soap or
detergent as you prefer and forget
grains-and you use phosphate
detergent, you rdso have no
problem.
